We're going to cover a lot in this tutorial, focusing on one topic at a time
and writing everything from scratch. As a warm up, though, it sure would be
nice to see some pixels on a screen.

Like other web development frameworks, Pyramid provides a number of "scaffolds"
that generate working Python, template, and CSS code for sample applications.
In this step we'll use a built-in scaffold to let us preview a Pyramid
application, before starting from scratch on Step 1.

Rather than starting from scratch, pcreate can make getting a Python
project containing a Pyramid application a quick matter. Pyramid ships with a
few scaffolds. But installing a Pyramid add-on can give you new scaffolds from
that add-on.

pserve is Pyramid's application runner, separating operational details from
your code. When you install Pyramid, a small command program called pserve
is written to your bin directory. This program is an executable Python
module. It is passed a configuration file (in this case, development.ini).
